* This species was discovered several years since by the late Mr. Dennis Murray, of Roxbury, 

 Mass., and'named Boletus Murraii, B. & C. (C. J. Sprague's MSS.). Under this name I have dis- 

 tributed it. Receatly it has been published in the " Grevillea," a London periodical, as Boletus 

 Sjjragueii, B. & C. Mr. Peck, of the New York botanical survey, several months before this 

 latter, published it as Boletus pictus. Peck, therefore liis name has the prioritj'.
